Notify when gEnv look-up fails
   Import commit f7d1b17bd23e7712f70b96735ea6c6e8d77ad65b

   Fixes for the 'dynamic' startup:
   - Set client flag so that VerifyDataSet can be submitted as parallel
   - SAve arguments to EnablePackage so that they can be used when replaying the issued commands
   - In stressProof: when in 'dyn' mode, skip some new tests which do not apply.
